Abstract

Purpose

In the process of conveying the solid–liquid two-phase medium of the centrifugal slurry pump, the wear of the flow-passing parts is an important problem affecting its life and safe operation. Therefore, a numerical investigation on the wear characteristics of the centrifugal slurry pump under different particle conditions was conducted.

Design/methodology/approach

A solid-liquid two-phase model based on CFD-DEM coupling is established and used to analyze the flow field and the wear characteristics of the flow-passing parts with different particle densities, volume fractions and sizes.

Findings

Particle conditions will affect the pump flow field. To analyze the pump wear characteristics, the wear distribution, wear value and cumulative force laws of flow-passing parts under different particle conditions are obtained. In each flow-passing part, with the increase of particle density, volume fraction and size, the wear area is concentrated and the wear depth increases. Under different particle conditions, the wear is mainly on the volute chamber and the blade pressure surface, and the tangential cumulative force of flow-passing parts is much larger than the normal cumulative force.

Originality/value

An accurate model and a coupled simulation method for predicting the wear of the slurry pump are obtained, and the wear characteristic law can provide a reference for the design of the slurry pump to reduce friction.

Abstract

Purpose

With changing employment conditions, technological advancement, frequent manpower reduction and global competition, the relevance of the protean and boundaryless career concepts is increasing. With this, the country’s culture plays a pivotal role in career choice. The purpose of this paper is to develop and validate protean and boundaryless career scales for college passing out students and in the Indian context. The protean career scale was measured by self-directed and values-driven dimensions, while the boundaryless career scale was measured by boundaryless mindset and organizational mobility preference.

Design/methodology/approach

The first step involved defining construct and determining face validity. The data collected via questionnaire from India’s final year engineering students were subjected to exploratory factor analysis and confirmatory factor analysis in the second and third steps, respectively. Finally, the nomological validity was tested by establishing the relationship between factors influencing career choice and newly developed protean and boundaryless career.

Findings

The result suggested using a two-factor model with a protean career (combining self-directed and values-driven items) and a boundaryless career as a separate construct for college passing out students.

Research limitations/implications

The developed scale has nine items that can be used to conduct surveys at the time of campus hiring by academic scholars, HR managers, and practitioners who are working on the identification, development and management of human talent as a part of any human resource management system.

Originality/value

To the best of the authors’ knowledge, this is the first approach to developing the protean and boundaryless career scale for college passing out students and in the Indian context which can be replicable for South Asian countries.

Abstract

Purpose

Auxiliary power system is an indispensable part of the train; the auxiliary systems of both electric locomotives and EMUs mainly are powered by one of the two ways, which are either from auxiliary windings of traction transformers or from DC-link voltage of traction converters. Powered by DC-link voltage of traction converters, the auxiliary systems were maintained of uninterruptable power supply with energy from electric braking. Meanwhile, powered by traction transformers, the auxiliary systems were always out of power while passing the neutral section of power supply grid and control system is powered by battery at this time.

Design/methodology/approach

Uninterrupted power supply of auxiliary power system powered by auxiliary winding of traction transformer was studied. Failure reasons why previous solutions cannot be realized are analyzed. An uninterruptable power supply scheme for the auxiliary systems powered by auxiliary windings of traction transformers is proposed in this paper. The validity of the proposed scheme is verified by simulation and experimental results and on-site operation of an upgraded HXD3C type locomotive. This scheme is attractive for upgrading practical locomotives with the auxiliary systems powered by auxiliary windings of traction transformers.

Findings

This scheme regenerates braking power supplied to auxiliary windings of traction transformers while a locomotive runs in the neutral section of the power supply grid. Control objectives of uninterrupted power supply technology are proposed, which are no overvoltage, no overcurrent and uninterrupted power supply.

Originality/value

The control strategies of the scheme ensure both overvoltage free and inrush current free when a locomotive enters or leaves the neutral section. Furthermore, this scheme is cost low by employing updated control strategy of software and add both the two current sensors and two connection wires of hardware.

Abstract

Purpose

This paper discusses how professionally qualified cisgender lesbian, gay, bisexual or queer (LGBQ) women youth workers present their self. The research examined how youth workers consciously or unconsciously shared their sexual identity with young people with whom they worked. Whilst this research focussed on youth workers, issues discussed are relevant for practitioners from a range of professional backgrounds such as therapists, social workers, teachers and health care practitioners. The research focused only on the experiences of cisgender LGBQ women as the experiences of men and trans women are different and so requires separate research.

Design/methodology/approach

This research taking a qualitative approach, used in-depth interviews to discuss how respondents shared information about their identity.

Findings

Some of fifteen youth workers interviewed reported not having choices about being out with the young people as their sexuality had been leaked. Others were able to pass and so choose when, or if, to be out with young people. Their different strategies to sharing information regarding their sexuality used by these participants reflected different approaches to being out.

Originality/value

Although there is evidence in the literature of how being out or closeted impacts on teachers there is little written about the effect on youth workers or other professionals. The little research that has been undertaken in this area focusses on the impact of identity on the clients rather than on the professionals. This article contributes to filling this gap in the literature.

Abstract

Purpose

General Data Protection Regulation (GDPR) of the European Union (EU) was passed to protect data privacy. Though the GDPR intended to address issues related to data privacy in the EU, it created an extra-territorial effect through Articles 3, 45 and 46. Extra-territorial effect refers to the application or the effect of local laws and regulations in another country. Lawmakers around the globe passed or intensified their efforts to pass laws to have personal data privacy covered so that they meet the adequacy requirement under Articles 45–46 of GDPR while providing comprehensive legislation locally. This study aims to analyze the Malaysian and Saudi Arabian legislation on health data privacy and their adequacy in meeting GDPR data privacy protection requirements.

Design/methodology/approach

The research used a systematic literature review, legal content analysis and comparative analysis to critically analyze the health data protection in Malaysia and Saudi Arabia in comparison with GDPR and to see the adequacy of health data protection that could meet the requirement of EU data transfer requirement.

Findings

The finding suggested that the private sector is better regulated in Malaysia than the public sector. Saudi Arabia has some general laws to cover health data privacy in both public and private sector organizations until the newly passed data protection law is implemented in 2024. The finding also suggested that the Personal Data Protection Act 2010 of Malaysia and the Personal Data Protection Law 2022 of Saudi Arabia could be considered “adequate” under GDPR.

Originality/value

The research would be able to identify the key principles that could identify the adequacy of the laws about health data in Malaysia and Saudi Arabia as there is a dearth of literature in this area. This will help to propose suggestions to improve the laws concerning health data protection so that various stakeholders can benefit from it.

Abstract

Purpose

The study applies Erving Goffman's (1974) “frame analysis” principles to examine how Sharia governance is practiced in Islamic banks and explores the interaction and strategies adopted by bank managers to influence the decisions of Sharia scholars. The study also aims to identify inherent flaws in the Sharia compliance review system.

Design/methodology/approach

The study employs the principles of Goffman as a lens to critically analyse a rich dataset obtained through interviews undertaken with 46 key players operating in the governance framework of the Malaysian Islamic banking industry due to its progressive Islamic governance framework.

Findings

The study demonstrates that managers of Islamic banks may engage in “passing” and “covering” strategies while interacting within the governance structure. Concurrently, Sharia boards (SBs) implement “protective practices” during their interactions, adding complexity to their responsibilities within the banks. Consequently, SBs cannot merely be viewed as instruments for legitimising banking operations. This raises questions about the “impression management,” “concealment” and “competence” strategies employed by managers and SB members, as suggested by Goffman's framework. These findings indicate that there is room for further enhancement in the governance practices of Islamic banks.

Research limitations/implications

Future research could explore aspects related to the governance of Islamic banks, such as investigating the independence and effectiveness of internal Sharia officers. Examining the strategies employed during their interactions with external Sharia boards and other stakeholders could provide further valuable insights.

Practical implications

By highlighting shortcomings in the governance and compliance review process, the findings could serve as a valuable resource for policymakers. The insights derived could inform the development of regulations aimed at reducing opportunistic behaviour and promoting accountability in the Islamic banking sector.

Originality/value

This study uniquely employs Goffman's concepts of “frontstage” and “backstage” strategies to offer insights into the interactions between Islamic bank managers and SBs and the impact of these interactions on Sharia compliance. The study contributes to the understanding of the dynamics between key players in the governance of Islamic banks and the factors influencing their adherence to Sharia principles.

Abstract

Purpose

The purpose of the paper is to investigate how judges and the general population formulate judgments on legal cases, considering both legal and extralegal factors, with a focus on the significance of the defendant’s sex.

Design/methodology/approach

The first experiment aimed to determine if non-lawyers’ judgments are affected by the defendant’s sex, using brief excerpts from indictments with the defendant’s sex interchanged. Study 2 aimed to verify if this effect applies to future lawyers, suggesting a peculiar approval granted by men to women displaying illegal sexual behaviour towards young men.

Findings

The findings showed that the sex of the offender only influenced judgments in sexual offences, with male participants being more lenient towards female offenders.

Originality/value

The originality/value of the paper lies in its examination of the influence of the defendant’s sex on judgments made by both judges and the general population, specifically focussing on non-lawyers’ judgments. While previous studies have shown that judges tend to be more lenient towards women in certain cases, this paper adds novelty by investigating whether a similar effect is observed among non-lawyers. Moreover, the research sheds light on the relevance of the defendant's sex in cases of sexual offences and identifies a gender-specific leniency towards female offenders, particularly among male participants. The study also explores how this effect might extend to future lawyers, providing insights into societal attitudes regarding illegal sexual behaviour involving women and young men. Overall, the paper contributes valuable information to the understanding of how sex-based biases can influence legal judgments and decision-making processes.

Abstract

Purpose

The purpose of this study was to investigate a framework for the implementation of freedom of information (FOI) legislation in South Africa, against Article 19’s nine principles of FOI legislation.

Design/methodology/approach

This qualitative study used semi-structured interviews to collect data from six experts selected by means of the snowball sampling technique and content analysis. The study used a modified Delphi design consisting of two rounds of interviews.

Findings

The results showed that little effort is made by government officials to demonstrate commitment to the implementation of FOI legislation.

Practical implications

The passing of FOI is expected to reduce corruption, increase public participation, reduce the level of secrecy and increase transparency and openness. This is not the case as the implementation of this socioeconomic right in South Africa is faced by numerous challenges, such as a lack of political will, secrecy laws providing for the opposite of what the FOI legislation seeks to achieve, poor legislative interpretation and a lack of clear policies. The study proposes a framework aimed at addressing these challenges.

Originality/value

The study provides a framework for the implementation of FOI legislation. The framework was developed under the guidance of Article 19 principles of freedom of information legislation.

Abstract

Purpose

Blood availability is critical for saving lives in various healthcare services. Ensuring blood availability can only be achieved through efficient management of the blood supply chain (BSC). A key component of the BSC is bloodmobiles, which are responsible for a significant portion of blood donation collections. The most crucial factor affecting the efficacy of bloodmobiles is their location selection. Therefore, detailed decision analyses are essential for the location selection of bloodmobiles. This study proposes a comprehensive approach to bloodmobile location selection for resilient BSCs.

Design/methodology/approach

This study provides a novel integration of the spherical fuzzy analytical hierarchy process (SF-AHP) and spherical fuzzy complex proportional assessment (SF-COPRAS) methodologies. In this framework, the criteria are weighted using SF-AHP. The alternatives are then evaluated using SF-COPRAS, employing criteria weights obtained from SF-AHP without defuzzification.

Findings

The results show that supply conditions and resilience are the most important criteria for a bloodmobile location selection. Additionally, the validation analyses confirm the stability of the solution.

Practical implications

This study presents several managerial implications that can aid mid-level managers in the BSC during the decision-making process for bloodmobile location selection. The critical factors revealed, along with their importance in choosing bloodmobile locations, serve as a comprehensive guide. Additionally, the framework proposed in this study offers decision-makers (DMs) an effective method for ranking potential bloodmobile locations.

Originality/value

This study presents the first application of multi-criteria decision-making (MCDM) for bloodmobile location selection. In this manner, several aspects of bloodmobile location selection are considered for the first time in the existing literature. Furthermore, from the methodological aspect, this study provides a novel SF-AHP-integrated SF-COPRAS methodology.
